Description

Technical Field

[0001] This utility model relates to the field of transfer device technology, and in particular to a transfer device for the production of plastic-coated pipes that is easy to load and unload. Background Technology

[0002] Plastic-coated pipes, also known as plastic-coated composite steel pipes, are steel-plastic composite pipes with a layer of plastic anti-corrosion coating fused to the inner surface of the steel pipe. These pipes have excellent corrosion resistance and low frictional resistance, and are widely used for transporting media such as water supply and drainage, seawater, warm water, oil, and gas. The main function of transfer devices is to move plastic-coated pipes from one production stage to the next, or from the production line to the storage area, thereby increasing the speed of transfer.

[0003] However, when using the plastic-coated pipe production transfer device, sometimes the plastic-coated pipes are inconvenient to load and unload and are easy to loosen and fall off during transportation, which may result in the plastic-coated pipes falling off or being damaged during transportation, making the device inconvenient to use. Utility Model Content

[0004] To solve the technical problems of inconvenient loading and unloading and easy loosening and falling during transportation of the above-mentioned plastic-coated pipes during production and transfer, this utility model provides a transfer device for plastic-coated pipe production that is easy to load and unload: including a fixing mechanism, a supporting mechanism and a limiting mechanism, wherein the supporting mechanism is provided with a fixing mechanism at the bottom and a limiting mechanism is movably installed at the right end of the supporting mechanism;

[0005] The fixing mechanism includes a mounting frame, the upper end of which is fixedly connected to the lower end of the first base. A first lead screw is rotatably mounted inside the mounting frame. A slider is threaded onto the surface of the first lead screw. Connecting rods are fixedly connected to both sides of the slider. A connecting block is fixedly connected to the right end of the connecting rod. The connecting block is fixedly connected to a limiting mechanism. The connecting rod is located in a sliding groove opened on both sides of the mounting frame and is slidably connected to the inner wall of the sliding groove.

[0006] Preferably, the limiting mechanism includes a second base, which is fixedly connected to the connecting block. A second protective frame is fixed to the top of the second base, and a second roller is provided at the lower end of the second base. Limiting frames are symmetrically arranged on the side of the second base near the first base, and the limiting frames are movably connected to the support mechanism.

[0007] Preferably, the support mechanism includes a first base, and the limiting frame is movably inserted into a socket on the first base; a first protective frame is fixed to the top of the first base, and a first roller is provided at the bottom of the first base.

[0008] Preferably, a second lead screw is rotatably connected to the left and right side walls of the first protective frame, and a lifting frame is threaded onto the two second lead screws.

[0009] Preferably, a threaded slider is engaged with the surface of the second lead screw, and both sides of the threaded slider are slidably connected to the limiting pressure plate. Auxiliary frames are symmetrically fixed at both ends of the limiting pressure plate, and a locking shaft is slidably connected inside the auxiliary frame. One end of the locking shaft is movably inserted into the insertion hole opened at the outer end of the threaded slider. A limiting piece is provided on the locking shaft, and a spring is sleeved on the locking shaft between the auxiliary frame and the limiting piece.

[0010] Preferably, support frames are fixedly connected to both the left and right sides of one end of the mounting frame, and the connecting rod is slidably connected to the support frames.

[0011] Preferably, a first rotating handle is fixed to one end of the first lead screw; a second rotating handle is fixedly connected to the upper end of the second lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a fixing mechanism to control the overall rightward displacement of the second base by rotating the first lead screw, thereby adjusting the limit of the second protective frame on the plastic-coated pipe, which facilitates the subsequent loading and unloading of the plastic-coated pipe.

[0014] 2. By pressing the limiting pressure plate down onto the plastic-coated pipe, the threaded sliders on both sides are pushed to contact the second lead screw. At this time, the locking shaft is locked into the inside of the threaded slider under the action of the spring, fixing the position of the threaded slider, thereby providing additional limiting for the plastic-coated pipe inside the device; by lifting the lifting frame, one end of the plastic-coated pipe is lifted, which drives the plastic-coated pipe to rise, thereby facilitating unloading and improving practicality.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Please see the appendix Figure 1-6 A transfer device for producing coated pipes that is easy to load and unload includes a fixing mechanism 1, a support mechanism 2, and a limiting mechanism 3. The fixing mechanism 1 is provided at the bottom of the support mechanism 2, and the limiting mechanism 3 is movably installed at the right end of the support mechanism 2. The fixing mechanism 1 includes a mounting frame 103, the upper end of which is fixedly connected to the lower end of the first base 201. A first lead screw 102 is rotatably installed inside the mounting frame 103. A slider 105 is threadedly connected to the surface of the first lead screw 102. A connecting rod 106 is fixedly connected to both the left and right sides of the slider 105. A connecting block 108 is fixedly connected to the right end of the connecting rod 106. The connecting block 108 is fixedly connected to the limiting mechanism 3. The connecting rod 106 is located in the sliding grooves 104 opened on both sides of the mounting frame 103 and is slidably connected to the inner wall of the sliding grooves 104.

[0025] When it is necessary to transfer the plastic-coated pipe, the first lead screw 102 is rotated to drive the slider 105 to move horizontally, thereby causing the connecting rods 106 fixedly connected to both sides of the slider 105 to drive the limiting mechanism 3 to move horizontally. This makes it convenient to adjust the holding space of the transfer device according to the actual length when loading and unloading the plastic-coated pipe, thus improving the flexibility of the device.

[0026] The limiting mechanism 3 includes a second base 301, which is fixedly connected to the connecting block 108. A second protective frame 302 is fixed to the top of the second base 301, and a second roller 304 is provided at the lower end of the second base 301. A limiting frame 303 is symmetrically provided on the side of the second base 301 near the first base 201, and the limiting frame 303 is movably connected to the support mechanism 2.

[0027] It should be noted that the distance between the second base 301 and the first base 201 can be flexibly adjusted by the limiting bracket 303.

[0028] The support mechanism 2 includes a first base 201, a limiting frame 303 movably inserted into a socket on the first base 201; a first protective frame 202 is fixed to the top of the first base 201, and a second lead screw 204 is rotatably connected to the left and right side walls of the first protective frame 202, and a lifting frame 205 is threaded onto the two second lead screws 204; a threaded slider 207 is engaged with the surface of the second lead screw 204; and a first roller 203 is provided at the bottom of the first base 201.

[0029] The surface of the second lead screw 204 is engaged with a threaded slider 207. Both sides of the threaded slider 207 are slidably connected to the limiting pressure plate 208. Both ends of the limiting pressure plate 208 are symmetrically fixed with auxiliary frames 209. A locking shaft 210 is slidably connected inside the auxiliary frame 209. One end of the locking shaft 210 is movably inserted into the outer end of the threaded slider 207. A limiting piece is provided on the locking shaft 210. A spring 211 is sleeved on the locking shaft 210 between the auxiliary frame 209 and the limiting piece.

[0030] When the plastic-coated pipe to be transported is placed inside the first protective frame 202, the limiting pressure plate 208 is pressed against one end of the plastic-coated pipe. Then, the threaded sliders 207 on both sides are pushed to contact the second lead screw 204. At this time, the locking shaft 210 is pulled outward. After the threaded slider 207 is engaged with the second lead screw 204, the locking shaft 210 is released. At this time, under the restoring force of the spring 211, the locking shaft 210 is engaged into the insertion hole opened at the outer end of the threaded slider 207, realizing the limiting of the limiting pressure plate 208 by the threaded slider 207, so that the plastic-coated pipe is subjected to downward pressure and limited, preventing it from scattering during transportation. When it is necessary to remove the plastic-coated pipe from the first protective frame 202, the second lead screw 204 can be rotated to drive the lifting frame 205 to rise, thereby lifting one end of the plastic-coated pipe for easy removal.

[0031] Now combined with the appendix Figure 1 —The implementation principle of this utility model is described as follows:

[0032] When using this device to transfer the coated pipe, first rotate the first handle 101 to drive the first lead screw 102 to rotate, causing the slider 105 to move horizontally within the mounting bracket 103, thereby driving the connecting block 108 on the connecting rod 106 to move horizontally, thus controlling the overall horizontal displacement of the second base 301. This adjusts the limit of the second protective frame 302 on the coated pipe, making subsequent loading and unloading of the coated pipe more convenient. The displacement distance of the second protective frame 302 can be adjusted according to the length of the coated pipe, offering high flexibility. After placing the coated pipe, press the limiting pressure plate 208 down onto the upper end of the coated pipe, and then push the threaded sliders 207 on both sides to contact the second lead screw 204. At this time, the locking shaft 210, under the restoring force of the spring 211, engages with the threaded slider. Inside the insertion hole of 207, the position of the threaded slider 207 is fixed, thereby providing additional limit for the plastic-coated tube inside the device to prevent it from falling during transportation. When it is necessary to unload the plastic-coated tube, first separate the second protective frame 302 from the first protective frame 202, then pull the locking shafts 210 at both ends to release the limit of the threaded slider 207, and then pull out the threaded slider 207 so that the threaded slider 207 is disengaged from the second lead screw 204, thereby releasing the pressure of the limiting pressure plate 208 on the plastic-coated tube. Then, rotate the second rotating handle 206 at the upper end of the first protective frame 202 to drive the second lead screw 204 to rotate, so that the lifting frame 205 moves upward along the second lead screw 204, thereby lifting one end of the plastic-coated tube to facilitate unloading and improve the transfer efficiency of the plastic-coated tube.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
